Guest Len919 Posted October 24, 2022 Report Share Posted October 24, 2022 Hello, I need to mount a cell phone booster antenna 60' above my cabin. (The cabin is on the side of a mountain and if I get my antenna 60' off the ground I'll have cell signal again). I'll be using a yagi style antenna and LMR400 cable to come back down to the booster. I want to mount it to a tree. But.. Thought I'd ask.... Does this create a significant lightning risk? Thank you Quote Link to comment Share on other sites More sharing options...
KAF6045 Posted October 25, 2022 Report Share Posted October 25, 2022 Any tall object is a lightning attractor. If there are other taller trees around it it is still a risk -- lightning could run down a tall tree and then jump to the antenna (it may appear as a better path to ground). Install a "lightning arrestor" with a GOOD ground connection -- though they don't stop an actual lightning strike; they work on EMP and induced surge currents from a nearby lightning strike, a direct hit would likely melt the coax and the arrestor, and merrily go on to the rest of the cabin wiring. Better to disconnect and ground the antenna coax itself when storms are nearby. Quote Link to comment Share on other sites More sharing options...
marcspaz Posted October 25, 2022 Report Share Posted October 25, 2022 60 feet of LMR400 will almost cometely attenuate 5g. (Like 60db) AdmiralCochrane and SteveShannon 2 Quote Link to comment Share on other sites More sharing options...
